I guess it could at some point be necessary to have fractions of satoshi. We will likely never know these things.
Discussion
Fractions of Satoshi will happen, in layer 2 first…. Maybe on the main chain.
Just food for thought… infinitely diminishing subsidy seems like an interesting element of predictability for the whole protocol… a sort of predictable but diminishing constant
Maybe our grandkids or great grandkids will have some fresh ideas to implement it if it makes sense…
Agreed that no one has any serious reason to fork the code over this today
